Valve Setting
To balance and preset the manifold
assembly, proceed as follows.
1. Using the chr
ome allen k
ey (6mm),
turn main valve clockwise until it
stops.
2. Using the small brass key, turn
memory stop clockwise until
it stops.
3.
Using the chrome allen k
ey
, turn
the main valve counter-clockwise to
set the loop flow or balancing turns
f
or that loop.
4. Using the small brass key, turn
memory stop counter-clockwise
until it st
ops.

How to Determine Balancing Turns
To balance the manifold correctly, determine the flow
(
gpm) and pressure drop (ft/hd) for each loop on
t
he manifold. To find the required turns, follow
directions below.
1. On the manifold to be balanced, find the loop with
the highest pressure drop (ft/hd). This loop does
not need any balancing, and will be fully open
(
4.25 turns from closed position).
2. To balance all other loops on the manifold, find the
p
ressure drop (ft/hd) for each loop and subtract from
the loop with the highest pressure drop (same as the
loop figured in step 1). The difference is the delta
ft/hd. Use this number on the balancing chart to
find the required number of balancing turns.
Example: If the highest pressure-drop loop has
7 ft/hd and the loop that needs to be balanced
has 5 ft/hd, subtract 5 from 7 for a difference of
2 delta ft/hd.
3. Locate the delta ft/hd number on the vertical scale
located on the left side of the balancing chart.
4. Locate the gallons per minute (gpm) on the horizontal
scale at the bottom of the balancing chart.
5. Locate where the delta ft/hd and gpm intersect
on the chart.
6. The closest diagonal line to this intersection represents
the number of full valve turns from closed to open to
accurately balance the loop. If the intersection falls
between two diagonal lines, estimate the distance
between the lines and adjust the turns accordingly.
